METHOD AND APPARATUS FORTREATING SELVAGE.

Specification of Letters Patent. Patented Aplelg, 1921.

Application filed July 12, 1919. Serial No. 310,347:

T 0 all whom it may concern I Be it known that 1, MARK A. REPLOGLE, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented new and useful Improvements in Methods and Apparatus for Treating Selvage, of which the following is a specification.

My invention relates toa method of treating selvage of fabric in order to render it of such a character that it may be suitably calendered and manipulated, and to an apparatus for practising the aforesaid method.

In weaving fabric to be utilized in various industries it has been customary to weave the edge in such a manner that the unraveling thereof will be prevented. In

some industries, notably that of pneumatic tire manufacture, it 1s necessary to calender the fabric, that is to say, to incorporate with it a rubber compound, and it has been found that the usual selvage edge is not well adapt ed to take upthis compound, since the fibers at the edge are not loose andpliable, but on the contrary are bound together and'more or less unflexible, and consequently the calenderingmaterial cannot be readily worked into the same. But even if the selvage could be properly calendered, it would still be thick and not readily workable to shape the fabric about the body.

Hitherto the practice has been to trim off this selvage,

cal trimming mechanism; and to discard l the trimmings, resulting in a considerable waste of material.

It is primarily the object of my invention provide a method for treating selvage which shall avoid all wastage, and at the same time more suitably prepare the fabric at the selvage for calendering, and for subsequently applying the fabric.

It is a further object of my invention to provide an apparatus which is adapted to pound, beat, or strike the fabric selvagc' uniformly in such a way as to bruise, break, loosen and elongate the fibers, so that they may more readily be incorporated with the calendering material and when so incorporated may be readily manipulated to be pressed into place.

A still further object of my invention is to pneumatic tires -practisin either by hand or by mechaniprovide means for determining the distance between the striking surface and that of the support for the material, whereby fabric of different thicknesses may be accommodated and uniformly treated.

More particularly, my method consists in treating the selvage, by beating it to flatten it out and loosen the fibers therein,

and is one, which may be uniformly,'efiiciently and economically practised by means.

an embodiment whereof of an apparatus,

is herein illustrated andwhichalso constitutes a part of my invention. 1

While my method and the apparatus for practising it may be broadly applied forofany fabric having a sel-V the treatment vage, I have found that they are particularly useful in treating the selvage of fabric to be calendered with a rubber compound for the manufacture of articles such :as'

and the like.

It is to be understood that my invention is not to be regarded as limited to any particular industry, however, nor thescope and extent thereof to any specific apparatus for g the method herein di'sclosed,.ex-

cept as defined by the claims, hereto ap-- pended and forming a part of this application. V j:

The following description when considered with reference to the accompanying drawings, wherein I have illustrated one form of an apparatus wherewith my invention may be practised, will afiord an un derstanding of both the method and an apparatus for carrying it out. 7 o

With reference to the drawings, wherein there has been illustrated a preferred embodiment of the invention, and throughout the severaliviews of which similar reference numbers. designate corresponding parts Figure 1 is a plan View of'an apparatus for practising my, method, the apparatus being shown as applied, to both edges ,of a

.strip of fabric;

Fig. 7 is a perspective view of the adjustable support shown in Fig. 6.

A strip of fabric 10 is caused to travel across a stationary mandrel 11, which is usually cylindrical in form, and rests in troughs 12, which are secured by any desired means, such as bolts, to a supporting bed 13. The mandrel should preferably be of a length approximately the same'as the width of the fabric, the selvage of which is being treated, and the means disclosed for supporting the mandrel, permits it ready replacement by a mandrel of the desired length and diameter. Thus by using a mandrel of greater diameter, a thinner fabric will be given the same degree of. treatment as a thick one, with a mandrel of lesser diameter.

Base members 14 are secured to the bed 13 at the outer ends thereof, each of said base members 14.- being provided with an offset dove-tail 15, which is adapted to fit with into a corresponding dove-tail groove 16 in a base 17 to which a motor 18 is bolted. i

A hand screw 19 is supported by anupstanding bracket 20, secured to or forming an integral part of the base member 14. One end of said hand screw 19 is provided with hand wheel 21 for operating the screw, while the other end of the screw is swiveled in base 17, thus permitting the adjustment of the motor toward and away from the edge of the fabric, so that the apparatus may accommodate varying widths of fabric.

A guiding flange 22is also bolted to the motor base 17 and is consequently moved with the motor and base. This flange 22 is provided with fingers 22 adapted to overlie the fabric as seen in Fi s. 1 and 2. p

The motor 18 is provided with the usual shaft 23, and to the shaft is keyed a substantially rectangular head 24'. This head comprises side pieces 25, connected by a pair of studs 26, passing through the ends of said side pieces 25, the studs 26 being provided with shoulders 27, to hold'the side pieces 25 properly spaced. Wheels or disks 28 having preferably beveled or curved edges are loosely mounted on the studs 26, which serve as axles therefor, by. being provided withcentral holes 28 which are appreciably larger than the studs 26, and through which the studs pass. Instead of wheels or disks 28, it is obvious that other elements having a different form, might be used, for example, spherical bodies.

While I have described but one apparatus, it will be understood that the apparatusis really in duplicate, one being located at each side of the fabric strip as clearly shown in Figs. 1 and 2. v V

From the above description of the appara- V such bloWs of great frequency. It will be understood that for efiicient operation the diameter of the mandrel should beselected such that the selvage will be pounded with the proper degree of force, such action being permitted by the loose mounting of the wheels 28. v The speed of travel of the fabric should alsobe so regulated that substantially the same surfaceof the selvage may be struck several times, so as to thoroughly bruise, break and loosen the fibers therein.

Referring now to Figs. 6 and 7, instead of having the mandrel 11 extend to the edge of the fabric, a shorter mandrel may be used, and at the end thereof, directly below the shaft 23 of the head 24;,is arranged an anvil 30, which serves as the striking surface over which the fabric selvage passes. The anvil 30 passes up through an aperture 31in a block 32, and is provided on its lower surface with a cam face 33, which abuts against a similar surface 3 1 of a wedge 35,so that the anvil 30 rests onth'e wedge." The wedge 35 is provided at its outer end with a dependinglug 36, having a slot for'receiving the end of a hand-screw 37, suitably supported in a bracket 38 upstanding from the base of'the block 32, as seen in Fig. 7. The wedge 35, by its adjustment forward or backward, by manipulation of the handscrew 37, thus raises and lowers the anvil 30, so that fabrics of different thicknesses may be treated. A set screw 40 may be used to firmly hold the anvil 30 in place, and

' the anvil support is suitably secured, as by bolts 11, to the bed 13/ Thus it will be seen that my method of treating selvage consists in pounding, striking or beating the selvage so as to break, loosen and elongate or flatten out the fibers therein, toprepare them for calendering and other manipulation, and while I have shown one type of apparatus suitable for practising the method, it will be understood that I donot mean to be limited'to anapparatus of the type shown, for it is readily apparent that not only may the method be carried out by hand, though not with the same degree of efficiency, as by pounding and bruising the selvage with a hammer, but it may be practised with numerous other forms of apparatus, which are easily conceivable,

as a machine that will apply a continuous series of successive blows by some vantages of my method,

rapidly reciprocating element, for example a trip hammer used for riveting, or by a rotating element provided with members which are thrown out centrifugally to strike the selvage as the element rotates.

Although certain reasons or been advanced as to the purposes and adit is to be understood that I do not desire to impose thereby any limitations to the scope of the appended claims.
